Games change. If something as simple as cosmetic pets really bothers you that much, you probably shouldn't be playing MMO's... Because there are far more people who DO like them than don't (NOTE: i said 'people', not 'players')
Also, thanks to the tressym's, 5 of my friends decided to try DDO, one is definitely buying the xpac, one is considering VIP, and the other 3 want to play more before they decide. All because i posted a picture of my "useless" cosmetic pet. And as far as how useless it is, it's proven great for guiding one of my friends through town/quests, since a flying kitty in a wizard's hat is something she can spot right away.
